December 22 is the 356th day of the year(357th in leap years) in the Gregorian calendar.Nine days remain until the end of the year.

A leap year is a calendar year containing one additional day added to keep the calendar year synchronized with the astronomical or seasonal year. Because seasons and astronomical events do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year.

The Gregorian calendar is the calendar used in most of the world. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average year 365.2425 days long, approximating the 365.2422-day tropical year that is determined by the Earth's revolution around the Sun. The rule for leap years is:

Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the year 2000 is.

History of China Account of past events in the Chinese civilisation

The earliest known written records of the history of China date from as early as 1250 BC, from the Shang dynasty, during the king Wu Ding's reign, who was mentioned as the twenty-first Shang king by the same. Ancient historical texts such as the Records of the Grand Historian and the Bamboo Annals describe a Xia dynasty before the Shang, but no writing is known from the period, and Shang writings do not indicate the existence of the Xia. The Shang ruled in the Yellow River valley, which is commonly held to be the cradle of Chinese civilization. However, Neolithic civilizations originated at various cultural centers along both the Yellow River and Yangtze River. These Yellow River and Yangtze civilizations arose millennia before the Shang. With thousands of years of continuous history, China is one of the world's oldest civilizations, and is regarded as one of the cradles of civilization.

Holidays and observances

Calendar of saints Christian liturgical calendar celebrating saints

The calendar of saints is a traditional Christian method of organizing a liturgical year by associating each day with one or more saints and referring to the day as the feast day or feast of said saint. The word "feast" in this context does not mean "a large meal, typically a celebratory one", but instead "an annual religious celebration, a day dedicated to a particular saint".

Anastasia of Sirmium Christian saint and martyr

Saint Anastasia is a Christian saint and martyr who died at Sirmium in the Roman province of Pannonia Secunda. In the Orthodox Church, she is venerated as St. Anastasia the Pharmakolytria, i.e. "Deliverer from Potions".

Eastern Orthodox Church Christian Church

The Eastern Orthodox Church, officially the Orthodox Catholic Church, is the second-largest Christian church, with approximately 200–260 million baptised members. It operates as a communion of autocephalous churches, each governed by its bishops in local synods, although roughly half of Eastern Orthodox Christians live in Russia. The church has no central doctrinal or governmental authority analogous to the Bishop of Rome, but the Ecumenical Patriarch of Constantinople is recognised by all as primus inter pares of the bishops. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played a prominent role in the history and culture of Eastern and Southeastern Europe, the Caucasus, and the Near East.
